The abbrevation "Patr." for "Patrone" is included in the designation of the complete round stencilled on packages or printed on package labels to indicate fixed Q.F. ammunition. The following are typical examples:–

"7,5 cm Pzgr.Patr. Kw.K. Bd.Z. f. 7,5 cm Pzgr."

"7,5 cm Nbgr.Patr. Kw.K. m. kl.A.Z. 23 Nb."

i.e., 7.5 cm, anti-tank gun, smoke cartridge with the small size of percussion fuze No. 23 for smoke shell.

In the designation of H.E. rounds the letters "Gr." without the prefix "Spr." are often used.

The markings on cases firming part of fixed rounds comprise stencillings round the side and base of the case and stampings in the base.

Stencilling on the side of cases is in black except the stencilling relating to propellant charges for use in hot climates, which is in red.

The following details are arranged in the sequence in which the markings are normally found between the approximate centre of the case and the flange at the base:–

The calibre, type and model numbers of the equipment for which the round is suitable are stencilled in the form "7,5 cm Kw.K. 40" (i.e., 7.5 cm tank gun, mo-del 40). Where a round is suitable for more than one equipment the designati-ons of the equipment are stencilled in sequence with the letter "u", signifying "and" as a conjunction.

The following abbrevations, used to indicate types of fixed, Q.F. equipment have been met with:–

The following markings are example of those added to the designation, normally the model number, to indicate equipments of foraign origin:–

The weight of the propellant charge in grammes is stencilled in the form of nu-merals, followed by the letter "g" below the details of the equipment, e.g., "164 g."

The nature, shape and size of the propellant are stencilled below the marking indicating the charge weight.

The following markings are used to indicate the nature of propellant:–

These letters in the case of double base propellants, are followed by figures or letters which also appears to relate to the composition. The shape of propel-lant is indicated by the following letters added to those used to indicate the nature:–

Bl.P.

Rg.P.

R.P.

Str.P.

The size of the propellant is given by a statement of the dimensions in millime-ters follwing the letters used to indicate the shape. The dimension figures are enclosed in a bracket and are arranged as follows with commas serving as de-cimal points:–

(Thickness, external diameter internal diameter), e.g., (1,9 x 15/4).

(Length with minus tolerance, external diameter/internal diameter), e.g., (175-2, 2/0,85). An "X" is sometimes used instead of the "–" bet-ween the lenght and the tolerance.

The following are typical examples of the complete markings used to indicate the nature, shape and size:–

The place and year of amnufacture of the propellant, followed by a mork-mark, are stencilled below the marking relating to nature, shape and size. The follow-ing is a typical example:–

"dgb 1941/3"

The place and date of the filling of the propellant charge, followed by a work-mark are stencilled below the marking relating to the manufacture of the pro-pellant, e.g., "On 17.6.42 x v."

The red stencilling used to indicate propellant charges of a reduced weighs for hot climates may be found near the base of the case, just above the flange, or higher up the side of the case, above the other stencilling. The marking used, "P.T. + 25° C" indicates that the normal or standard charge temperature on which the weight of the charge is based is 25° C. (e.g., 77° F). The German standard charge temperature for normal European temperatures is 10° C. (i.e., 50° F).

In some instances cases are stencilled "Abgebr. Ldg." in red. This marking as found near the base (corresponding to the position of the "P.T. + 25° C" mark-ing) and refers to the propellant charge. The marking probably indicates propel-lant charges of low stability which are to be given priority in expenditure.

The position of the following markings are as viewed with the case turned so that the stamped letters and numbers on the base are upright.

Distinctive markings on script lettering which indicate the nature, and in some in-stances the model number, of the projectile are stencilled in white or black paint to the left above the primer hole. The markings used indicate the type of the shell, and are the same as those given above under "Projectile Nomenclature".

In some instances the Roman numerals indicating the weight classification of the projectile are stencilled in white to the right below the primer hole.

Fig. 15 gives the normal positions and signifiance of base stampings. The model number, below the primer hole, is followed by the letters "St." when the case is of steel.

The abbrevations following the calibre of the equipment, stamped below the model num-ber of the case, are the same as those given in the details of stencilling on the side of the case.

The markings on the bags are the same as those stencilled on the side of the case ex-cept that the calibre, type and model number of the equipment are not included.
